WATER-VAPORIZER.

Application filed April 5, 1919. Serial No. 288,410.

To all whom it may concern Be it known that I, WELLINGTON P. Km-

DER, a citizen of the United States, and a resident of Boston, in the county of-Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Water-Vaporizers, of which the following is a full, clear, and exact specification. r

The object of this invention is the construction of an attachment whereby either watery vapor, or watery vapor mixed with air in any desired proportions, can at will be admitted to the carburetor or to theintake manifold.

My invention consists essentially of a waintake manifold.

In the drawings forming part of this specification, Figure 1 is a side view of an attachment embodying my improvements. Fig. 2 is a detail sectional View of the an valve, looking from the opposite side.

Referring to Fig. 1, the reference character 1 designates a water tank designed to be snugly clamped against the exhaust manifold of the engine, 2 being the manifold and 3 the clamps or other attaching devices.

Preferably at the midlength of the tank 1 is a stand pipe 4 connected near its outer end with a tube 5 which communicates with the intake manifold 6, the stand pi e 4 terminating in a filling funnel 7. At t e opposite side of the stand pipe from the end of the pipe 5 is a boss 9 into which is screwed a threaded plug or valve 10 turned by a knurled hand piece 11 in convenient reach of the chauffeur. Thus valve 10 normally closes the air inlet 12, shown in Fig. 2, so that by unscrewing the valve until the inlet 12 is internally exposed, air may be admitted from the atmosphere to the stand p1pe 4.

The filling funnel 7 is closed ordinarily by a screw plug 13 actuated by a knurled thumb piece 15.

The operation of the device 1s as follows: The screw plug 13 having been unscrewed, water is poured through the funnel 7 until the tank 1 is nearly filled, under conditions of summer temperatures. During winter weather, the tank may be partially filled w th water, allowing for ice expansion, without injury. Then the plugis screwed tlghtly into place, and the vaporizer permitted to operate. As the water within 'the tank is heated by the exhaust within the manifold 2, vapor arises therefrom 'andescapes through the stand pipe 4 and pipe 5 v into the intake manifold 6.

The hand piece 11 being in convenient reach of the driver, he can at will turn the same until a desired supply of air is admitted to the stand pipe or dome 4, and passes therefrom with the vapor to the intake manifold 6. A partial turn admits a sl ght amount of air; and a further turn, a larger amount of air, according as the chauffeur wlshes a leaner mixture for the engine, or otherwise. The chief advantages of this device are its extreme simplicity in construction and economy of manufacture. It is automatically operative at all times. Can be immediately adjusted to admit air with the vapor in any desired proportion. The vapor dome is made the filling device. The entire vaporizer is readily attached to any engine,

the other terminal portion of said cross passage having an air inlet laterally therein, and .a screw plug screwing into said terminal portion to adjustably' var the air inlet, and having means in the reac of the chauffeur for turning said screw plug.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 31st day of March, 1919.
